question 20 of 25
by visual inspection, determine the best - fitting regression model for the scatterplot.
a. exponential
b. linear
c. no pattern
d. quadratic

Explanation:

A quadratic regression model forms a parabolic shape. Looking at the scatter - plot, the data points seem to follow a U - shaped (parabolic) pattern. An exponential model would show either rapid growth or decay (a curve that gets steeper or flatter in one direction). A linear model would show a straight - line trend. Since there is a clear U - shape, it is not a no - pattern situation.

Answer:

D. Quadratic
